PhD dissertation
Reconfigurable Intelligent Metasurfaces for Wireless Communication and Sensing Applications
Ph.D. dissertation, Virginia Tech · 2022
Metasurfaces are electrically thin arrays of sub-wavelength scattering elements (meta-atoms) that control electromagnetic waves through engineered surface boundary conditions. This dissertation develops reconfigurable metasurfaces, with active components embedded in each meta-atom, for programmable radiation patterns, integrated communications systems where the RF aperture and transceiver live in the surface itself, metasurface-enabled direct signal modulation, and deep-learning-based metasurface design.
